Study of Condensate Absorption Capacity in Exposed Soil when Water Recedes at the Bottom of Hoh Xil Lake, Qinghai

A study on Qinghai Hoh Xil's exposed sandy lake bottom reveals that artificial water-retention layers significantly enhance condensate absorption capacity compared to bare ground, with unidirectional condensation occurring three times more frequently and total condensate volumes being 2.588 times greater under these conditions. Conducted using a micro-osmometer in July 2021, the research examined condensate variation, formation time, volume, and absorption capacity across artificial water-retention layers and bare ground, both underpass and sealed conditions. Findings indicate that permafrost influences condensation dynamics, with zero-flux surface transport occurring within 30 cm of the soil surface. The study provides critical insights for vegetation restoration in ecologically degraded lake bottom areas.
